              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Winds started kicking up around 16:45. Did not perform test slews during chekcout due to high winds. Winds slowed down enough we could open at 19:00.  We observed for a few hours, but then dust spiked around 20:30 and we had to close again. The dust went away, but winds stayed high until 00:30. As winds dropped, precip appeared just to the north of us on radar. It was headed our way, but dried up before getting here. Unfortunately, the clouds from this stuck around, as we found when we opened. We could not even get a focus star. We staryed open in the hopes a hole would form or the clouds would break. It eventually cleared enough to get data, and we stayed open until twilight.
